I think there is no such filter for the meta widget.
Since for a filter “widget_title”, the breakpoint works fine during debugging.
add_filter('widget_title', 'change_widget_title');

I removed unneeded links directly from the file, but there may be a filter or a hook
\wp-includes\widgets\class-wp-widget-meta.php
<li><a href="<?php echo esc_url( get_bloginfo( 'rss2_url' ) ); ?>"><?php _e( 'Entries feed' ); ?></a></li>
<li><a href="<?php echo esc_url( get_bloginfo( 'comments_rss2_url' ) ); ?>"><?php _e( 'Comments feed' ); ?></a></li>
